A judge has ruled a taped interview of an alleged killer conducted as part of a sociology study off-limits to Montreal police, The Globe and Mailreported. Luka Magnotta, a stripper and porn actor accused of killing and dismembering a 33-year-old Chinese student, participated in a study on the sociology of sex work conducted by two University of Ottawa professors in 2007, five years before the alleged murder took place. After reviewing a transcript of the tape, Justice Sophie Bourque of the Quebec Superior Court ruled that while the right to confidentiality in academic research is not absolute and must be weighed against other societal goals, in this case the harm to academic research done in releasing the tape would outweigh the benefit.
